Extend support writing linear least squares problems to disk.

1. Make the mechanism for writing problems to disk, generic and
controllable using an enum DumpType visible in the API.

2. Instead of single file containing protocol buffers, now matrices can
be written in a matlab/octave friendly format. This is now the default.

3. The support for writing problems to disk is moved into
linear_least_squares_problem.cc/h

4. SparseMatrix now has a ToTextFile virtual method which is
implemented by each of its subclasses to write a (i,j,s) triplets.

5. Minor changes to simple_bundle_adjuster to enable logging at startup.
